An example of parasitism in the rainforest is leeches and any animal. Leeches are parasites, attaching to and feeding off of the blood of animals. According to parasitic relationships, this benefits the leeches while harming the animals.
After it rains in rain forests, leeches can be found among the leaf litter on the ground. As animals move across the floor of the forest, the leeches attach to the animals and feed off their blood. Although this can harm the animals, it does not kill them. As soon as the leeches are full, they drop off their hosts. Micro hematophagus arachnids, mosquitoes and ticks both also feed on the blood of their hosts.
Another example of parasitism in the rainforest is botfly larvae and jaguars. Botflies lay their eggs on jaguars and other animals. Once the eggs hatch, the larvae grow to maturity by feeding on the flesh of the jaguar.
There is a long parasitic relationship between ants and fungus. Some species of fungus merely use ants as a method of transportation. They attach to the ants' bodies and detach once they reach the colony's fungus garden. Once in the garden, they take over. Another species of fungus kills the ants and uses their bodies to reproduce.
